FW-1216
Message <timestamp>, [FW-1216], <sequence-number>,, INFO, <system-name>, <Label>, value
has changed(High=<High value>, Low=<Low value>). Current value is <Value> <Unit>.
Probable Cause Indicates that the number of arbitrated loop physical address (AL_PA) cyclic redundancy check
(CRC) errors has changed. This indicates that errors have been detected in the FC frame. Invalid
CRC messages occur when the number of CRC errors in Fibre Channel frames for specific source ID
(S_ID) and destination ID (D_ID) pairs change. These messages might also be caused by dirty
equipment, temperature fluctuations, and aging equipment.
Recommended
Action
Verify that your optical components are clean and function properly. Replace deteriorating cables or
small form-factor pluggables (SFPs). Check for damage from heat or age. You should set your high
boundaries to five- or six-digit figures, as only large numbers of messages indicate a problem in this
area.
Severity INFO
FW-1217
Message <timestamp>, [FW-1217], <sequence-number>,, INFO, <system-name>, <Label>, is
below low boundary(High=<High value>, Low=<Low value>). Current value is <Value>
<Unit>.
Probable Cause Indicates that the number of arbitrated loop physical address (AL_PA) cyclic redundancy check
(CRC) errors has fallen below the low boundary. This indicates that errors have been detected in the
FC frame. Invalid CRC messages occur when the number of CRC errors in Fibre Channel frames for
specific source ID (S_ID) and destination ID (D_ID) pairs change. These messages might also be
caused by dirty equipment, temperature fluctuations, and aging equipment. You should set your
high boundaries to five- or six-digit figures, as only large numbers of messages indicate a problem
in this area.
A low level of invalid CRC errors means that the switch is functioning normally.
Recommended
Action
No action is required. Respond to this message as is appropriate to the particular policy of the
end-user installation.
Severity INFO
FW-1218
Message <timestamp>, [FW-1218], <sequence-number>,, WARNING, <system-name>, <Label>, is
above high boundary(High=<High value>, Low=<Low value>). Current value is <Value>
<Unit>.
Probable Cause Indicates that the number of cyclic redundancy check (CRC) errors has risen above the high
boundary. This indicates that errors have been detected in the FC frame. Invalid CRC messages
occur when the number of CRC errors in Fibre Channel frames for specific source ID (S_ID) and
destination ID (D_ID) pairs change. These messages might also be caused by dirty equipment,
temperature fluctuations, and aging equipment.
